SAMUEL F. REYNOLDS, OF AUBURN, NEW YORK.

METAL-ROLLING MACHINE.

SPECIFICATION forming part of Letters Patent No. 236,085, dated December` 28, 1880.

Application filed July 3, 1880. (Model.)

To all whom it may concern:

Be it known that l, SAMUEL F. REYNOLDS, of Auburn, in the county of Cayuga and State ot' New York', have invented certain new and useful Improvements in Dies for Forming Metal; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters ot' reference marked thereon, which form a part ot' this specification. Y

This invention relates to certain new and useful improvements in rolling-machines, having for its object to improve the operation of the same; and it consists in the construction4 and arrangement of parts as will be hereinafter more fully set forth.

In the annexed drawings, which fully illustrate my invention, Figure l is a section on line x x, Fig. 2. Fig.2 is a section on liney y, Fig. 1. Fig.3 is a detail view ofthe die; and Fig. 4 is a modification.

Like letters of reference indicate like parts.

rEhis machine is designed for rolling axles, hanne-staples, &c.,.where it is desired to break down the ends of a piece of metal and form a shoulder thereon.

A represents the bed, B the top plate, and C the sides, ot' theframe ofthe machine. The sides C are provided with the openings a., for the introduction of the metal.

D D are two sliding plates, having the chucks b, for the reception of the dies E E E E, said dies being held in position by the set-screws c. The dies are arranged upon either end-of the sliding plates, and the racks F are placed'in the center of same. These racks are engaged by a pinion, G, arranged upon a shaft, H, said shaft being' provided with an arm, I, to which is secured a connecting-rod, J. The connecting-rod J is attached at its other end to a wheel, K, which is revolved by suitable gearing, by which means there is imparted to the pinion G an intermittent rotary motion to move the racks and sliding plates back and forth in opposite directions.

5o L is a gage, adjusted by means of set-screws,

and having a roller, d, which bears against the metal when between the dies, and prevents the same from sliding thereon, thereby insuring the rolling.

The sliding plates are provided with the ribs e, which tit in corresponding grooves f in the bedv and top plate, to insure the proper movement of the plates.

It will be observed that the upper die, E, is slightlyT inclined. The metal is introduced between these dies E E', the gage having rst been properly adjusted, and the said metal is broken down to the size desired, leaving the same in a partly-finished state. The metal is then placed between the straight dies E E", which round it off, leaving it without any iiat spots.

In making wagon-axles, car-pins, and Work of this kind, that requires a collar or shoulder, I first make the dies with a groove through the face the shape of the collar or shoulder desired. I then place the dies in the chucks, and adjust them to the size of the axle or pin Wanted. The metal is then vheated and placed against the gage betweenKthe bevel and straight dies and broken down. The metal is then placed between the straight dies and rounded up or finished.

In Fig. et I have shown a modification, which is, that the dies may be made with the straight bottomy surface and the upper straight and beveled surface, thereby saving two sets of' dies; but this wold require a machine to move the plates double the distance, and I therefore prefer the two sets ot' dies.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

In a rolling-machine, the sliding plates moving in oppositedirections and carrying the racks, chucks, and dies, and the gage L, adapted to rest between the dies and adjusted substantially as and in the manner set forth.

In testimony that I claim the foregoing as my own I have hereto aflixed my signature in presence of two witnesses.

SAML. F. REYNOLDS.
